San Antonio Spurs coach Gregg Popovich is notorious for being terse during his in-game interviews. But he had some serious diarrhea of the mouth during Sunday's playoff game against Dallas. And it was for good reason.

Popovich was being interviewed by Craig Seger Jr. because the elder Seger is absent from his well-known sideline gig while battling leukemia. Popovich took off his usual curmudgeonly exterior to wish Seger well.

Nothing short of classy.
